Hi, this information is not preserved in the DPDK mbuf structure, so is lost after the call to rx-burst. The DPDK port field stores the port number on return from rx_burst, but your app could look to reuse this field to store the queue number also. For example, if you have only a few input ports, you could encode the port number in the high bits of the "port" field, and store the rx queue in the lower bits. This could be done as an rx-callback if you want to avoid adjusting your app following each and every rx-burst call. /Bruce
